The most I've ever had to pay for ups over cpost was about $12. Totally worth it considering they've always been on time (usually a couple days early!) and no damage. hell, they always even seem happy to be bringing me my packages!
I did however just receive a package through cpost that was a whole day early and the guy finally came to my door with it! (same guy who dumps slip in community box without even trying the house. My neighbors have had the same problem) I guess cpost finally told him to do his job!
I just received a non-airsoft related package through DHL. Those guys must ship via F-18 or something. Crazy fast shipping!
